Answer:
85
Step-by-step explanation:
60+60+70+80+85 = 355
355/5 = 71
highest common factor of 20 and 30=10
there will be 5 pens in each box.
Step-by-step explanation:
I think you are trying to find x, I dunno, but if you are here's the solution.
when trying to find x, your main goal is to shift all x terms to one side.
For the first one
4x-3 = 5x-3
Carry all x terms to one side:
(4x-3)-5x = (5x-3)-5x
4x-5x-3 = -3
Shift all constants (purely just numbers, no x) to the other side
(4x-5x-3)+3 = (-3)+3
4x-5x = 0
-x = 0
x = 0
The second one:
-2x = 3x-5
5x = -5
x = -1
Done, have fun with math!
